[0002] During prone ventilation, the patient lies prone with arms bent on both sides of the head and legs straight. Soft pillows are placed under the chest, abdomen, hips and ankles of the patient. The head can be tilted to one side. Prone ventilation is suitable for patients who undergo lumbar and back examinations or cooperate with pancreatic and cholangiography examinations, as well as patients who cannot lie flat or sideways after spinal surgery or have wounds on the waist, back and buttocks, and patients with abdominal pain caused by gastrointestinal bloating. During prone ventilation, the traditional method is to let the patient lie prone on a soft pillow. However, this method is less comfortable and can easily cause numbness and soreness in the limbs and muscles, making it impossible for the patient to maintain a prone position for ventilation for a long time. In addition, when the patient switches between lying flat and prone positions, the soft pillow needs to be adjusted, which is very inconvenient to use. In order to solve the problems brought by the traditional methods, the present invention has designed this prone ventilation support device, which has a waterbed-like structure and can achieve effective fit with the head, chest, abdomen and hips.

[0043] like Figure 1-Figure 12 As shown, a prone position ventilation support device provided in this embodiment is installed on a bed board 1, and a groove is provided on the bed surface of the bed board 1. The prone position ventilation support device includes a water bag 2, a circulating water supply mechanism 3 and a shaping mechanism. The bottom surface 202 of the water bag 2 is installed in the groove of the bed board 1, that is, the bottom surface 202 of the water bag 2 is attached to the groove of the bed board 1, ensuring that the water bag 2 is effectively spread flat and fixed on the bed board 1.

[0044] The shaping mechanism includes a reel assembly, a guide seat 64 and a brake assembly 61; the water bag 2 is connected to the circulating water supply mechanism 3; there are multiple shaping mechanisms, and the multiple shaping mechanisms are arranged side by side at equal intervals along the width direction of the water bag 2; the reel assembly includes a reel body 60 and a pull rope 63, the reel body 60 is located outside the water bag 2, and the guide seat 64 and the brake assembly 61 are both located inside the water bag 2.

[0045] Corresponding to each shaping mechanism: the number of the reeling and unwinding components, guide seats 64 and brake components 61 are all multiple, the guide seat 64 is a U-shaped structure, the brake component 61 is provided with a guide groove, the multiple brake components 61 are arranged side by side at equal intervals along the length direction of the water bag 2, and the brake component 61 is connected to the bottom surface 202 of the water bag 2, two adjacent brake components 61 are provided with a guide seat 64, and the guide seat 64 is connected to the top surface 201 of the water bag 2, one end of the pull rope 63 is connected to the reeling and unwinding body 60, the pull rope 63 is inserted from one end of the water bag 2 in the length direction, and after passing through the U-shaped grooves of multiple guide seats 64 and the guide grooves of multiple brake components 61 at the same time, the other end of the pull rope 63 is connected to the other end of the water bag 2 in the length direction.

[0046] The retractable winding body 60 is used for reeling in and unreeling the pull rope 63, and the brake assembly 61 is used for braking and releasing the pull rope 63; when the pull rope 63 is braked by the brake assembly 61, the pull rope 63 is fixed and cannot move; when the brake assembly 61 releases the pull rope 63, the pull rope 63 can move on the brake assembly 61.

[0047] When this embodiment is used, the circulating water supply mechanism 3 and the retractable reel body 60 can be placed under the bed to avoid being exposed to the outside and causing problems such as unsightly. In this embodiment, water is filled into the water bag 2 through the circulating water supply mechanism 3, the retractable reel body 60 controls the reeling and unreeling of the drawstring 63, and the brake assembly 61 controls the braking and release of the drawstring 63. In this way, the height of the corresponding water bag 2 is controlled by the cooperation of the circulating water supply mechanism 3, the retractable reel body 60 and the brake assembly 61, so that the water bag 2 can be effectively fitted with the head, chest, abdomen and hip of the human body, with high comfort, so that the patient can maintain a prone position for ventilation for a long time, and can assist the patient to turn over, which is very convenient to use.

[0048] See also Figure 1 As shown, there are five shaping mechanisms, and the specific number of shaping mechanisms is determined according to factors such as the width of the water bag 2, and this is not limited. At the same time, the number of reeling and unreeling components, guide seats 64, and brake components 61 in each shaping mechanism is determined according to factors such as the width of the water bag 2 and the length of the water bag 2, and this is not limited.

[0049] In this embodiment, the guide seat 64 is connected to the top surface 201 of the water bag 2, the brake assembly 61 is connected to the bottom surface 202 of the water bag 2, and after the pull rope 63 is inserted into the water bag 2, it passes through multiple U-shaped grooves of the guide seats 64 and multiple guide grooves of the brake assemblies 61 at the same time, so that the pull rope 63 connects the top surface 201 and the bottom surface 202 of the water bag 2 together, so that when the circulating water supply mechanism 3 fills water into the water bag 2, the height of the corresponding part of the water bag 2 after being filled with water can be controlled by controlling the length of the pull rope 63 between two adjacent brake assemblies 61.

[0050] When the device of this embodiment is in the initial state, there is no water in the water bag 2, the water bag 2 is in a flat state, the retractable body 60 reels the pull rope 63, the pull rope 63 between two adjacent brake assemblies 61 is short, and the guide seat 64 is close to the bottom surface 202 of the water bag 2. Figure 1 and Figure 2In the lying position shown, the brake components 61 corresponding to the chest, abdomen and hips are first placed in a braking state, so that the drawstring 63 between two adjacent brake components 61 is restricted, so that the stretch is in an initial shorter state, and the brake component 61 corresponding to the head is in a loose state, at this time, the circulating water supply mechanism 3 fills water into the water bag 2, and the retractable reel body 60 unwinds, due to the filling of water, the drawstring 63 between the two adjacent brake components 61 corresponding to the head will become longer due to the filling of water, the water bag 2 will expand and bulge higher, and the drawstring 63 between the two adjacent brake components 61 in the braking state cannot move due to the braking restriction, so the water bag 2 corresponding to the chest, abdomen and hips will not bulge due to the filling of water, and will still be in a flat state, but there will be a certain amount of water filled, so that the free switch from the initial state to the lying position is completed. According to the height of the bulge of the water bag 2 corresponding to the head, the retractable reel body 60 unwinds the drawstring 63 of the corresponding length, and the circulating water supply mechanism 3 fills the water bag 2 with corresponding water.

[0051] When Figure 1 and Figure 2 When the supine position shown is switched to the prone position, the prone position requires that the water bag 2 corresponding to the chest, abdomen and hips should be raised and become higher, and the water bag 2 corresponding to the head should be lowered to a certain extent compared with the chest, abdomen and hips. The specific operation process is as follows:

[0052] First, the brake components 61 corresponding to the chest, abdomen and hips are changed from the braking state to the released state, while the brake components 61 corresponding to the head are in the released state. Then, the circulating water supply mechanism 3 fills water into the water bag 2, and the reel body 60 is unwound, so that the pull rope 63 between two adjacent brake components 61 becomes longer due to the filling of water. Since all the brake components 61 in the water bag 2 are in the released state, the water bag 2 is raised as a whole and becomes higher. Then, the brake components 61 corresponding to the chest, abdomen and hips are changed from the released state to the braking state, so that the adjacent brake components 61 are The length of the pull rope 63 between the components 61 is limited by the brake, so that the height of the water bag 2 corresponding to the chest, abdomen and hip will not be lowered due to the retracting and unreeling body 60 retracting the pull rope 63. Then the retracting and unreeling body 60 reels a certain length of the pull rope 63, so that the length of the pull rope 63 between the two adjacent brake components 61 corresponding to the head becomes shorter, so that the height of the water bag 2 corresponding to the head becomes lower to a certain extent, and then the retracting and unreeling body 60 stops reeling, and the circulating water supply mechanism 3 stops filling water into the water bag 2, so that the free switching from the lying position to the prone position is completed. The specific amount of lowering of the height of the water bag 2 corresponding to the head depends on the actual situation, which is not limited. Similarly, when switching from the prone position to the lying position, the corresponding control of the circulating water supply mechanism 3, the brake component 61 and the retracting and unreeling body 60 can be completed, and this will not be elaborated in detail.

[0053] When Figure 1 and Figure 2 The shown supine position is switched to the side-lying position, that is, when assisting the patient to turn over, the specific operation process is as follows:

[0054] First, the brake components 61 corresponding to the chest, abdomen and hips are changed from a braking state to a released state, while the brake components 61 corresponding to the head are in a released state. Then, the circulating water supply mechanism 3 fills water into the water bag 2, and the retractable reel body 60 is unwound, so that the pull rope 63 between two adjacent brake components 61 becomes longer due to the filling of water. Since all the brake components 61 in the water bag 2 are in a released state, the water bag 2 bulges as a whole and becomes higher. Then, the brake components 61 on one side of the water bag 2 are changed from a released state to a braking state, while the brake components 61 on the other side of the water bag 2 are still in a released state. Then, the retractable reel body 60 corresponding to the other side of the water bag 2 is reeled, so that the pull ropes 63 of the two adjacent brake components 61 corresponding to the other side of the water bag 2 become shorter, so that the height of the other side of the water bag 2 becomes the lowest state, and thus the patient's turning from one side of the water bag 2 to the other side is completed. Similarly, when the patient is assisted to turn over by changing from the prone position to the side-lying position, the corresponding control of the circulating water supply mechanism 3, the brake assembly 61 and the retractable and retractable winding body 60 can be completed, which will not be elaborated in detail.

[0055] In this embodiment, no matter the patient is in a supine position, prone position or side-lying position, the circulating water supply mechanism 3 will fill a certain amount of water into the water bag 2, so the device of this embodiment has a water bed structure as a whole. Through the cooperation of the circulating water supply mechanism 3, the retractable and reeling body 60 and the brake assembly 61, the height of the corresponding water bag 2 is controlled. When the patient lies on the device of this embodiment, the water bag 2 can be effectively fitted with the head, chest, abdomen and hip of the human body, with high comfort, and different states can be freely switched, which is quite convenient to use.

[0056] In the process of freely switching between different states, the circulating water supply mechanism 3 fills the water bag 2 with water, or the water bag 2 returns water to the circulating water supply mechanism 3, depending on the state change and the actual situation. At the same time, when the retractable and unretractable body 60 of this embodiment freely switches between different states, whether it is the retracting pull rope 63 or the unretracting pull rope 63, and the length of the retracting pull rope 63 and the length of the unretracting pull rope 63 are determined according to the state change and the actual situation.

[0057] When the device of this embodiment changes from the initial state to the lying state, the brake components 61 corresponding to the chest, abdomen and hips are in the braking state, and the retractable and reeling body 60 will unwind a certain length of the drawstring 63, so that the water bag 2 corresponding to the head becomes higher, and then the retractable and reeling body 60 stops unwinding. Therefore, when the patient lies flat on the device of this embodiment, the stability of the water bag 2 can be guaranteed, and the water bag 2 can effectively support the patient. Similarly, the water bag 2 is also stable in the prone state and the side-lying state.

[0058] In this embodiment, the pressure of the water filled into the water bag 2 by the circulating water supply mechanism 3 is determined according to the actual situation, which is not limited. In this embodiment, when the user is in the prone position, a soft pillow can be placed corresponding to the ankle, and when the prone position is switched to the side-lying or lying position, the soft pillow can be removed or not.

[0059] In this embodiment, the portion of the pull rope 63 exposed outside the water bag 2 is protected by a flexible protective cover 5, and the flexible protective cover 5 is elastic and can be bent. In this embodiment, the bed board 1 is preferably provided with a plurality of positioning grooves 101, which are the same in number and opposite in position as the pull rope 63, and the pull rope 63 passes through the positioning grooves 101 and then enters the water bag 2. The positioning grooves 101 play a positioning function of the pull rope 63 on the bed board 1, and at the same time, the portion of the flexible protective cover extending to the bed board 1 covers the positioning grooves 101 to protect the pull rope 63 from being exposed.

[0060] The present embodiment is further preferred, the brake assembly 61 includes a first electromagnet 612, a first iron core 613, a slider 611 and a brake seat 610, the brake seat 610 is connected to the bottom surface 202 of the water bag 2, the brake seat 610 is an inverted U-shaped structure, and the guide groove is formed between the U-shaped groove on the brake seat 610 and the bottom surface 202 of the water bag 2; the brake seat 610 is provided with a slide groove connected to the guide groove, and the slider 611 is movably installed at the slide groove; the bottom surface 202 of the water bag 2 is provided with a first mounting hole opposite to the position of the slide groove, the first electromagnet 612 is installed at the first mounting hole, and the first iron core 613 is located in the groove of the bed board 1 and surrounds the first electromagnet 612.

[0061] The working principle of the brake assembly 61 of this embodiment is as follows: when the first electromagnet 612 is energized, the first electromagnet 612 attracts the slider 611 to move toward the first electromagnet 612, so that the pull rope 63 is clamped by the slider 611 and the first electromagnet 612, so that the pull rope 63 is braked and cannot move; when the first electromagnet 612 is de-energized, the first electromagnet 612 has no attraction to the slider 611, and as the water in the water bag 2 is filled, under the pressure of the water, the pull rope 63 can move between the slider 611 and the first electromagnet 612. The provision of the first iron core 613 can further increase the magnetic force of the first electromagnet 612, so that the braking effect is better.

[0062] In this embodiment, in order to ensure that the first electromagnet 612 does not cause harm to the human body due to contact with the water in the water bag 2 during the process of gaining and losing power, preferably, the voltage that triggers the first electromagnet 612 is only 12V or less, which is very low and will not cause harm to the human body.

[0063] See also Figure 8 As shown, in this embodiment, it is further preferred that the slider 611 is provided with an extension edge 6110 on a side close to the pull rope 63, the extension edge 6110 is located in the guide groove, and the extension edge 6110 is provided on both sides of the slider 611 in the length direction. In this way, under the combined action of the slider 611 and the extension edge 6110, the contact area between the brake assembly 61 and the pull rope 63 during braking can be increased, thereby improving the braking effect.

[0064] In the present embodiment, the reel body 60 further preferably comprises a first mounting seat 601, a second mounting seat 602, a reeling roller 603, a transmission roller 604, a synchronous belt 607, a synchronous gear 606, a motor 605 and a pressure roller 608. The first mounting seat 601 and the second mounting seat 602 are arranged in parallel and alternately along the length direction of the water bag 2, and the first mounting seat 601 is close to the water bag 2; the reeling roller 603 and the transmission roller 604 are rotatably mounted on the first mounting seat 601 and the second mounting seat 602 respectively; the conveying surface of the synchronous belt 607 is provided with teeth, And the non-conveying surface is a plane; one end of the synchronous belt 607 is connected to the winding roller 603, and after the synchronous belt 607 passes around the transmission roller 604, the other end of the synchronous belt 607 is connected to one end of the pull rope 63; the synchronous gear 606 and the pressure roller 608 are both rotatably installed on the first mounting seat 601; the synchronous gear 606 is meshed with the synchronous belt 607; the number of the pressure rollers 608 is two, the two pressure rollers 608 press the non-conveying surface of the synchronous belt 607, and the two pressure rollers 608 are located on both sides of the synchronous gear 606.

[0065] When the reeling and unreeling body 60 of this embodiment is used, the motor 605 is started, driving the synchronous gear 606 to rotate, and under the action of the synchronous belt 607, driving the reeling roller 603 and the transmission roller 604 to rotate, thereby driving the pull rope 63 to reel and unreel. When reeling, the synchronous belt 607 is reeled on the reeling roller 603. Under the action of the two pressure rollers 608, this embodiment ensures the effective meshing of the synchronous gear 606 and the synchronous belt 607, and ensures the effective transmission of motion.

[0066] In this embodiment, the retractable and reeling body 60 further includes a transition belt 609, both sides of which are planes, and the other end of the synchronous belt 607 is connected to one end of the pull rope 63 through the transition belt 609. When the retractable and reeling body 60 is reeled, and the synchronous belt 607 is completely reeled on the reeling roller 603, the transition belt 609 will contact the synchronous gear 606. Since there are no teeth on the transition belt 609, the rotation of the synchronous gear 606 will not drive the transition belt 609 to move, so that the pull rope 63 will not be reeled again, that is, the pull rope 63 has reached the maximum reeling limit. Therefore, the design of the transition belt 609 effectively ensures that the pull rope 63 will not be reeled again when the maximum reeling limit is reached, so as to avoid excessive reeling and affecting the service life of the device of this embodiment.

[0067] In the present embodiment, the shaping mechanism further comprises a supporting assembly 62 and a brake assembly 65, both of which are located in the water bag 2, and the number of the supporting assembly 62 and the brake assembly 65 are both multiple, and each supporting assembly 62 is equipped with a corresponding brake assembly 65, and the number of the supporting assemblies 62 and the guide seat 64 is the same and the positions are opposite; the supporting assembly 62 comprises a fixing seat 620, a first connecting rod 621, a second connecting rod 622, a third connecting rod 624 and a fourth connecting rod 623, and the fixing seat 620 is connected to the bottom surface 202 of the water bag 2; the first connecting rod 621 and the second connecting rod 622 are connected to the bottom surface 202 of the water bag 2; the first connecting rod 621 and the third connecting rod 624 are connected to the bottom surface 202 of the water bag 2; the first connecting rod 621 and the fourth connecting rod 623 are connected to the bottom surface 202 of the water bag 2; the first connecting rod 621 and the third connecting rod 624 ... One end of the second connecting rod 622 is hinged to the two sides of the guide seat 64, one end of the third connecting rod 624 and the fourth connecting rod 623 are hinged to the two sides of the fixed seat 620, the other end of the first connecting rod 621 is hinged to the other end of the third connecting rod 624, the other end of the second connecting rod 622 is hinged to the other end of the fourth connecting rod 623, and a parallelogram connecting rod structure is formed among the first connecting rod 621, the second connecting rod 622, the third connecting rod 624 and the fourth connecting rod 623; the brake assembly 65 is installed on the fixed seat 620, and is used for braking and releasing the parallelogram connecting rod structure.

[0068] The working principle of the support assembly 62 and the brake assembly 65 of this embodiment is as follows: a parallelogram linkage structure is formed between the first link 621, the second link 622, the third link 624 and the fourth link 623 to support the guide seat 64, so that under the action of the parallelogram linkage structure, the guide seat 64 and the water bag 2 are supported at a corresponding height position. When the parallelogram linkage structure supports the guide seat 64 at a corresponding height position, the brake assembly 65 brakes the parallelogram linkage structure, so that the parallelogram linkage structure will no longer be adjusted, so that the guide seat 64 will be stably maintained at the corresponding height position, that is, the corresponding water bag 2 will be stably maintained at the corresponding height position.

[0069] Taking the case where the two adjacent brake assemblies 61 corresponding to the guide seat 64 are in the released state as an example, as the water in the water bag 2 is filled, if the brake assembly 65 does not brake the parallelogram linkage structure, the pull rope 63 of the two adjacent brake assemblies 61 will become longer, the guide seat 64 will move in the direction away from the bottom surface 202 of the water bag 2, and the parallelogram linkage structure will follow the movement of the guide seat 64, so that the corresponding part of the water bag 2 bulges. If the parallelogram linkage structure is braked by the brake assembly 65, even if the two adjacent brake assemblies 61 are in the released state, due to the action of the parallelogram linkage structure and the brake assembly 65, the length of the pull rope 63 of the two adjacent brake assemblies 61 will not become longer, so the corresponding part of the water bag 2 is still maintained at the original height position, so that the height of the corresponding part of the water bag 2 is controlled separately. Under the action of multiple support assemblies 62 and brake assemblies 65, this embodiment can realize the separate control of the height of different parts of the water bag 2, thereby realizing the free shaping of the water bag 2, which can better fit the human body and has high comfort.

[0070] Under the action of multiple support components 62 and brake components 65, this embodiment can achieve independent control of the heights of different parts of the water bag 2. Therefore, the water bag 2 can be freely molded into different states, and is not limited to the lying position, prone position and side-lying position, but can also be molded into other states. Moreover, it can be freely molded according to the body shapes of different human bodies and can effectively fit the human body.

[0072] The working principle of the brake assembly 65 of this embodiment is as follows: when the second electromagnet 651 is energized, the second electromagnet 651 attracts the brake block 650 to move toward the direction of the second electromagnet 651, so that the inclined surface structure 6501 of the brake block 650 contacts the annular sleeve 626, and the brake block 650 clamps the annular sleeve 626 of the third connecting rod 624 and the fourth connecting rod 623, so that the third connecting rod 624 and the fourth connecting rod 623 cannot rotate relative to the fixed shaft 625, thereby realizing the braking of the parallelogram linkage mechanism; when the second electromagnet 651 is de-energized, the second electromagnet 651 has no attraction to the brake block 650, and the third connecting rod 624 and the fourth connecting rod 623 can rotate relative to the fixed shaft 625, so that the parallelogram linkage mechanism can freely telescope. The setting of the second iron core 652 can further increase the magnetic force of the second electromagnet 651, so that the braking effect is better.
